Description
Technical Field
The present disclosure relates to the field of communications technologies, and in particular, to an antenna parameter configuration method, a multi-antenna device, and a storage medium.
Background
The wireless communication module is widely applied to the IOT industries such as PC, wireless gateway and the like. With the progress of cellular communication, the LTE wireless communication module is upgraded from LTE to LTE-A version, and the rate is increased from 150Mbps to more than 1 Gbps. To support higher rates, 4x4MIMO technology has evolved, i.e., wireless communication modules need to support 4 antennas to support higher downlink throughput rates. And the rate of the 5G wireless communication module can even reach 10Gbps, and the 4X4MIMO technology is the basic configuration.
According to the 3GPP protocol, the wireless communication module can report the antenna capacity supported by the wireless communication module to the base station, and the base station can also send air interface data according to the number of the antennas supported by the wireless communication module when the data is downloaded. In this case, if the antennas are not matched (for example, the wireless communication module supporting 4X4MIMO is connected to only two antennas), the 4X4MIMO data of the base station cannot be effectively demodulated due to the lack of two antennas, resulting in a decrease in data throughput rate. The performance of the wireless communication module is even lower than a wireless communication module supporting 2x2MIMO and configured to connect dual antennas. Therefore, in practical application, the corresponding number of antennas must be actually configured according to the number of antennas supported by the module.
For the whole machine design of the client, the new whole machine usually supports 4 antennas at the beginning of the design, but the original whole machine design is mostly double antennas, and the new whole machine cannot support 4 antennas structurally. Even in the case of a design where the whole machine supports 4 antennas, there are cases where it is configured as a dual antenna according to the height of the whole machine configuration or other requirements. How to apply a wireless communication module supporting the 4x4MIMO technology to a dual antenna/4 antenna complete machine is a problem that manufacturers of wireless communication modules have to face.
To solve this problem, the current method is as follows:
1. for 4 antennas, two software versions are output from the double antennas, corresponding to two module models.
There are disadvantages: two module models result in a doubling of module authentication costs. Research and development testing investment, as well as production/inventory management costs, may also rise.
2. The module reserves a hardware pin, and the starting-up detects the state of the hardware pin, so as to configure the number of the module antennas.
There are disadvantages: a module pin is added, for example, an m.2 module, and the m.2 module protocol does not have a functional definition of this pin. Meanwhile, after pins are added, the whole machine of the customer also needs to modify hardware design, and the compatibility of the module is greatly reduced.
3. The number of the open module antennas is configured by software, and parameters are configured by a customer.
There are disadvantages: because the customer needs to additionally provide a station to configure the parameter, and meanwhile, the module needs to be restarted to perform the antenna connectivity test after configuration, so that the test time is increased, the configuration of different complete machines is managed, and the cost of the customer is increased.

Detailed Description
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present application based on the embodiments herein.
Fig. 1 is a block diagram of a multi-antenna device according to an embodiment of the present application, where in one case, the multi-antenna device may be a wireless communication module. The wireless communication module is designed for 4X4MIMO antennas and comprises M, M1, M2 and 4 antennas in total.
MIMO technology refers to the use of multiple transmitting and receiving antennas at a transmitting end and a receiving end, respectively, so that signals are transmitted and received through the multiple antennas at the transmitting end and the receiving end, thereby improving communication quality. The system can fully utilize space resources, realize multiple transmission and multiple reception through a plurality of antennas, can doubly improve the system channel capacity under the condition of not increasing frequency spectrum resources and antenna transmitting power, shows obvious advantages and is regarded as a core technology of next generation mobile communication. The essence of MIMO technology is to provide spatial diversity gain and spatial multiplexing gain for the system to increase data throughput, effectively improving spectral efficiency.
The wireless communication module can be connected with 4 antennas at most, but in practical production application, not all antennas can be connected and used. When all the 4 antennas are connected, the wireless communication module is 4 antennas; when only M and D/G antennas are connected, the wireless communication module is a dual antenna. When the wireless communication module is provided with 4 antennas or double antennas, different antenna parameters are configured. After the wireless communication module is produced, the number of the connected antennas is fixed, so that corresponding antenna parameters need to be configured for the multi-antenna device according to the specific number of the connected antennas.
Of course, fig. 1 is only one illustrative example of the present application. The number of antennas to which the multi-antenna device can be connected, and which combinations of antennas to connect to, are determined according to the actual antenna resources. In addition, in other embodiments, the multi-antenna device of the present application may also be a wireless communication device including the wireless communication module set described above.
Fig. 2 is a flowchart of an antenna parameter configuration method according to an embodiment of the present application. Referring to fig. 2, the method includes the steps of:
s100: and monitoring the current working frequency band in real time.
Wireless communication networks are widely deployed to provide various communication services such as telephony, video, data, messaging, broadcast, and so on. Multi-antenna (multiple input multiple output, MIMO) technology is widely used in wireless communication technology.
According to the 3GPP protocol, the communication frequency band between the base station and the multi-antenna device may change, and the data types of the communication between the multi-antenna device and the base station are different from each other. Different types of data require different numbers and types of antennas for demodulation.
The current operating frequency band is the frequency band of the current base station for communication with the multi-antenna device. The current working frequency band is specifically that the network is registered after the multi-antenna device is started in an RF signaling mode, and the current RF working frequency band is used.
S200: and if the current working frequency band is in the target frequency band, acquiring the antenna connection state of the multi-antenna equipment.
In particular, the multi-antenna device is a wireless communication device. The working frequency band corresponds to the data type, and the multi-antenna device receives the data of different data types through the antenna in different working frequency bands. That is, data of different data types requires different kinds and numbers of antennas for efficient reception and demodulation.
The target frequency band is a communication frequency band supporting the maximum MIMO capability of the multi-antenna equipment. Where the maximum MIMO capability is the MIMO capability that the multi-antenna device has when all antennas in the multi-antenna device are connected. The MIMO capability of a multi-antenna device is determined by the type and number of antennas that the device successfully connects to. Whether the current working frequency band is in the target frequency band or not is judged, whether the multi-antenna device has the maximum MIMO capability or not is judged in the target working frequency band, the interference and influence of the working frequency band on the judging process and the result are eliminated as far as possible, and the accuracy of parameter configuration is improved.
The antenna connection state includes whether each antenna is connected or not, or the number and kind of connected antennas.
S300: and configuring antenna parameters of the multi-antenna device according to the antenna connection state.
Specifically, the multi-antenna device corresponds to different MIMO capabilities according to the connection state of the antennas. For example, configured as 4 antennas, the multi-antenna device is provided with a first MIMO capability; configured as dual antennas, the multi-antenna device is provided with a second MIMO capability. Different MIMO capabilities require configuration of corresponding antenna parameters to enable the multi-antenna device to function properly for signal reception and demodulation.
The maximum MIMO capability of the wireless communication module can be determined by acquiring the antenna resources of the multi-antenna equipment. The maximum MIMO capability may be a MIMO capability supported by an antenna actually connected to the multi-antenna apparatus or may be a MIMO capability not supported by an antenna actually connected to the multi-antenna apparatus.
Taking fig. 1 as an example, the antenna resource of the wireless communication module supports at most 4 antenna connections, and thus the maximum MIMO capability is 4x4MIMO capability.
According to the antenna parameter configuration method, the wireless communication equipment can automatically configure the antenna parameters according to the antenna connection state of the wireless communication equipment, and the design, development and maintenance cost of the multi-antenna equipment is reduced; the compatibility of the multi-antenna equipment is improved, and the risk of additionally increasing pin definition and modifying the hardware design of a client is avoided; the testing cost of the client caused by parameters to be configured is reduced, and the product management cost is reduced.
In one embodiment, step S200 specifically includes:
s210: the received signal strength of each antenna in the multi-antenna device is obtained.
S220: and judging whether each antenna in the multi-antenna equipment is successfully connected according to the signal intensity.
Specifically, the antenna connection state characterizes the connection state of each antenna in the multi-antenna device, including successful connection and unsuccessful connection. Because the current working frequency band is in the target frequency band, under the current working frequency band, if each antenna is successfully connected, each antenna can receive signals with certain signal strength. If the antennas are in an unsuccessful connection state, the signal strength received by the antennas which are not successfully connected is very weak. The signal strength is specifically an indication of the signal strength received by RSSI (Received Signal Strength Indication).
From the above analysis, it can be determined whether each antenna is successfully connected or not by the signal intensity received by each antenna. The signal strength received by an antenna that is successfully connected will be above a certain strength threshold and the signal strength received by an antenna that is not successfully connected will be below a certain strength threshold.
In a specific embodiment, step S220 specifically includes: if the signal strength is higher than the first strength threshold, judging that the corresponding antenna is successfully connected; if the signal strength is lower than the second strength threshold, judging that the corresponding antenna connection is unsuccessful; wherein the first intensity threshold is greater than the corresponding second intensity threshold.
Specifically, the signal strength received by each antenna corresponds to a first strength threshold and a second strength threshold, wherein the first strength threshold is greater than the second strength threshold. Comparing the intensity of the signal received by the antenna with a first intensity threshold value and a second intensity threshold value respectively, and judging that the antenna is in a connection state if the intensity of the signal received by the antenna is higher than the first intensity threshold value; if the received signal strength is below the corresponding second strength threshold, the antenna is determined to be in an unconnected state. The signal strengths of the unconnected and connected received antennas are very different, and therefore the first strength threshold is much greater than the second strength threshold.
Of course, the first intensity thresholds corresponding to all the antennas may take the same value or may take different values; the second intensity threshold may take the same value or may take a different value.
Taking the wireless communication module of fig. 1 as an example, if the signal strength received by the antenna M is greater than the corresponding first strength threshold A1, the signal strength received by the antenna M1 is greater than the corresponding first strength threshold A2, the signal strength received by the antenna M2 is greater than the corresponding first strength threshold A3, and the signal strength received by the antenna D/M is greater than the corresponding first strength threshold A4, the antenna connection state of the multi-antenna device is configured as 4 antennas (i.e., all the 4 antennas are connected).
If the signal strength received by the antenna M is greater than the corresponding first strength threshold A1, the signal strength received by the antenna M1 is less than the corresponding second strength threshold B2, the signal strength received by the antenna M2 is less than the corresponding second strength threshold B3, and the signal strength received by the antenna D/M is greater than the corresponding first strength threshold A4, the antenna connection state of the multi-antenna device is configured as a dual antenna (i.e., the antenna M and the antenna D/M are connected, and the antennas M1 and M2 are not connected).
Wherein, the values of A1-A4 can be the same, can be partially the same, or can be different; the values of B1-B4 may be the same or partially the same or different.
If the signal intensity received by the antenna does not belong to any of the conditions, the antenna is disconnected, or part of the antenna is in poor contact.
After the complete machine assembly of the wireless communication device is completed, the function of the complete machine needs to be tested, which includes the RSSI test of the wireless communication module, and the RSSI test of the wireless communication module is realized through steps S210-220, so that the RF function and the antenna connectivity of the wireless communication module can be detected.
In a specific embodiment, the first intensity threshold and the second intensity threshold may be fixed values or dynamic values. If a fixed value, it is preset by the developer.
And if the dynamic value is the dynamic value, calculating according to the intensity of the signal received by the antenna through an algorithm. Since the signal strength received by the antenna is related to the distance between the antenna (wireless communication device) and the base station, in addition to whether the antenna is connected or not. Therefore, the dynamic value obtained through algorithm calculation more comprehensively considers the influence of various factors on the signal strength, and a more accurate strength threshold value can be obtained, so that the real connection state of the antenna can be more accurately judged.
In one embodiment, the antenna connection status includes the type and number of successfully connected antennas. The step S300 specifically includes: and configuring antenna parameters of the multi-antenna device according to the types and the number of the successfully connected antennas.
Specifically, the multi-antenna device includes M, D/G, M four antennas M2. The application provides a MIMO capability corresponding to a MIMO mode. For example, a 4x4MIMO capability corresponds to a 4x4MIMO mode and a 2x2MIMO capability corresponds to a 2x2MIMO mode.
The step S300 specifically includes: if the M, D/G, M four antennas M2 are successfully connected, configuring the antenna parameters of the multi-antenna equipment as parameters corresponding to the 4X4MIMO mode;
if M, D/G two antennas are successfully connected, M1 and M2 two antennas are not successfully connected, and the antenna parameters of the multi-antenna device are configured as parameters corresponding to a 2X2MIMO mode.
More specifically, multiple sets of antenna configuration parameters are stored in the multi-antenna device in advance, for example, the antenna connection state of 4 antennas corresponds to parameters corresponding to a 4x4MIMO mode, and the antenna connection state of two antennas corresponds to parameters corresponding to a 2x2MIMO mode. Therefore, according to the antenna connection state, a corresponding set of antenna parameters can be selected from the prestored multiple sets of antenna parameter configurations to perform parameter configuration on the multiple antenna equipment.
According to the antenna parameter matching method, the antenna parameters are configured to be corresponding antenna parameter values, and antenna hardware resources of the multi-antenna equipment can be matched with the antenna parameters, so that the multi-antenna equipment can work in a proper working mode.
Taking fig. 1 as an example, if the wireless communication module is configured as dual antennas, the antenna parameters of the multi-antenna device are configured according to candidate antenna parameter values corresponding to the 2X2MIMO operation mode. If the wireless communication module is configured as 4 antennas, the antenna parameters of the multi-antenna device are configured according to target antenna parameter values corresponding to the 4X4MIMO working mode.
In one embodiment, prior to step S100, the method further comprises the steps of:
s010: and acquiring the antenna parameter configuration state of the multi-antenna equipment.
In particular, the antenna parameter configuration state characterizes whether antenna parameters of the multi-antenna device are configurable.
The step S100 specifically includes: if the antenna parameter configuration state is configurable, the current working frequency band is monitored in real time.
Specifically, if the antenna parameter configuration state is not configurable, no subsequent steps need to be performed. When the antenna parameter configuration state is configurable, representing that the antenna parameters of the multi-antenna equipment are in an unconfigured state or the configuration state needs to be changed; at this point, it makes sense to perform the subsequent steps.
In one embodiment, step S010 specifically includes:
s011: acquiring an antenna configuration flag bit of multi-antenna equipment;
s012: and judging whether the antenna parameters of the multi-antenna equipment are configurable according to the antenna configuration zone bit.
Specifically, the antenna parameters of the multi-antenna device are configurable and non-configurable, and the values of the antenna configuration flag bits are different. For example, an antenna configuration flag bit value of 1 indicates that the antenna parameter is configurable; an antenna configuration flag bit value of 0 indicates that the antenna parameters are not configurable.
If the antenna connection state is in other states than the above two states, the antenna parameter configuration state of the wireless communication module is kept as a configurable state, which represents that the antenna is not connected or part of the antenna is in poor contact.
When the antenna connection state is detected not to belong to any preset state, errors can be reported to research and development engineering personnel in an early warning mode, so that the research and development engineering personnel can timely and quickly solve the connection problem of the multi-antenna equipment, and the multi-antenna equipment is normally connected. The antenna parameter configuration state of the multi-antenna device is not set to an unconfigurable state until the multi-antenna device parameter is successfully set.
In one embodiment, the method further comprises the steps of:
s600: after the antenna parameter configuration is completed, the antenna configuration state of the multi-antenna device is set to be non-configurable.
Specifically, the antenna connection state of the multi-antenna device is not required to be changed if not changed. Setting the antenna configuration state to be non-configurable may prevent the multi-antenna device from unnecessarily performing the previous steps again. And meanwhile, the stability of antenna parameters is ensured.
Specifically, for example, setting the antenna configuration flag bit to 0 corresponds to turning off the adaptive configuration antenna parameter function.
The antenna parameter configuration method can be applied to an actual network of an operator; the method can also be applied to the antenna test process of the whole production stage of the wireless communication equipment, and the influence of a real network can be avoided at the moment, so that the scheme is simpler and more efficient to operate.
Through the method and the device, the original testing scheme is still kept unchanged in the whole plant, and the testing cost and the management cost are not additionally increased. Taking fig. 1 as an example, during an antenna test process in a whole production stage of an apparatus, a communication frequency band needs to be artificially adjusted to a frequency band supporting 4x4 MIMO.
By the method and the device, two wireless communication modules are not required to be configured for the wireless communication equipment, so that the production cost is saved, and the research and development test cost is reduced; hardware pins are not required to be reserved, so that the compatibility of the wireless communication equipment is enhanced; and the open software configuration is not needed, so that the test time and the labor cost are saved. According to the antenna connection state self-adaptive configuration method, the antenna parameters are configured in a self-adaptive mode according to the actual antenna connection state, high automation is achieved, manpower and material resources are saved, product research and development cost and production cost are reduced, and product compatibility is improved. In addition, the technical scheme of the application is not only suitable for LTE wireless communication modules, but also can be applied to 5G wireless communication modules, and is wide in application range.
It should be understood that, although the steps in the flowchart of fig. 2 are shown in sequence as indicated by the arrows, the steps are not necessarily performed in sequence as indicated by the arrows. The steps are not strictly limited to the order of execution unless explicitly recited herein, and the steps may be executed in other orders. Moreover, at least some of the steps in fig. 2 may include multiple sub-steps or stages that are not necessarily performed at the same time, but may be performed at different times, nor do the order in which the sub-steps or stages are performed necessarily performed in sequence, but may be performed alternately or alternately with at least a portion of the sub-steps or stages of other steps or other steps.
